Benefits of Shanxi Rubber TPE Manufacturers

TPE uses overmolding injection process, common products such as handles, grips, electronic materials, etc.

Diene transparent TPE, diene TPE is mainly an isomer of natural rubber, so it is also called thermoplastic trans-natural rubber. Although its heat resistance and mechanical strength are not as good as rubber, due to its good transparency, weather resistance, electrical insulation, and photodegradability, it is widely used in shoemaking, sponges, optical films, and other industrial rubber products, etc.

To achieve the matte appearance characteristic of thermosetting rubber surfaces, a rougher mold surface is required. Generally speaking, the rough surface produced by electrical discharge machining (EDM) on the mold cavity will result in an excellent workpiece appearance and make demolding relatively easy. Abrasive methods such as steam blasting, sandblasting, or shot blasting, as well as chemical etching, can also be used to create surfaces with different gloss and appearance.

The material gives the product a comfortable touch, improves grip, enhances product aesthetics and added value. Most products are exported to developed countries and regions such as the United States, Japan, and the European Union.

TPE overmolding injection generally uses a two-shot injection process, that is, the injection-molded rigid plastic part is fixed in the overmolding mold,

Transparent TPE materials have different product properties when applied in different aspects. Thermoplastic elastomer, also called TPE material, transparent TPE not only has the processing properties of thermoplastic plastics but also has the physical properties of vulcanized rubber. This is the so-called advantageous combination of plastic and rubber advantages. Transparent TPE is widely used in people's daily life and production.

SEBS is the product of hydrogenation of SBS. SEBS has a saturated molecular structure, which makes its characteristics very different. It has the necessary aging resistance, yellowing resistance, and other traits for producing transparent TPE, and also contributes to excellent properties such as high temperature resistance and corrosion resistance. This is how transparent TPE is made.

Then, at the appropriate temperature, the TPE soft material is injection overmolded onto the hard plastic part, and after cooling, the product is obtained. The injection temperature for overmolding varies depending on the hard plastic material being overmolded.

During the molding process of TPE material, during the filling of the mold cavity,

Transparent TPE is used in stationery, sports equipment, etc. It has good UV resistance, chemical resistance, and is easy to color and process.

Since any impurities in TPE material can affect the transparency of the product, attention must be paid to sealing during storage, transportation, and feeding to ensure the TPE raw material is clean. Especially if the TPE raw material contains moisture, heating will cause the material to deteriorate, so it must be dried. During injection molding, a drying hopper must be used for feeding.

If the filling performance of the product is poor, there will be too much pressure reduction, excessively long filling time, unqualified filling, etc., causing product quality issues.
